The saturation current I SATURATION should be chosen to be above the maximum value of I LIMIT . The inductor should
have very low DC resistance (DCR) to reduce the I R power losses - high DCR values will reduce efficiency.

Inductor L DCDC
The fast switching frequency (4MHz) of the AS3647/47B allows for the use of small SMDs for the external inductor.

11.Can be adjusted in I C mode with register coil_peak (see page 24)
1. Do not exceed maximum I SATURATION - can be ensured by setting coil_peak (will limit LED current)
2. Flash pattern: 200ms/3A, 200ms pause, 200ms/3A, 2s then repeat again (no limit on the number of total cycles)
Alternative pattern with 1000ms/1.6A, 200ms pause, 200ms/3A, 200ms pause, 200ms/3A, 2s then repeat
again. (no limit on the number of total cycles)
3. Set current limit to 2A ( coil_peak =00b) - will limit maximum output current.
Flash cycle limit: 150ms on, 500ms off; repeat maximum 50 times.
4. Set current limit to 2.5A ( coil_peak =01b) - will limit maximum output current.
5. Set current limit to 3.0A ( coil_peak =10b) - can limit maximum output current.
6. Set current limit to 2.5A ( coil_peak =01b) - will limit maximum output current.
7. Set current limit to 2A ( coil_peak =00b) - will limit maximum output current.
If a different inductor is chosen, ensure similar DCR values and at least0.6μH inductance at I LIMIT .
